Maximum password length supported by kernel: 256 Minimum password length supported by kernel: 0 Hashes: 2 digests 2 unique digests, 2 unique saltsīitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates extended_luks_header passphrases-dictionary $ hashcat -force -hash-type 14600 -attack-mode 0 -outfile recovered_passphrase. To perform dictionary attack using hashcat version 5.1.0 you need to force execution (in case that OpenCL does not have any GPU available), define LUKS hash type, attack mode (straight), file to store found passphrase, file that contains possible passphrases, and extended LUKS header backup. The state file contains basic information and current progress. Warning: restoring state, ignoring options -b, -e, -f, -l, -m and -s. Warning: using dictionary mode, ignoring options -b, -e, -l, -m and -s.

$ bruteforce-luks -t 4 -v 60 -w state_file -f passphrases-dictionary luks_header_backup To perform dictionary attack using bruteforce-luks version 1.3.1 you need to define the number of threads (see additional notes section), amount of time between printing progress information, session file that can be used to continue attack later, a file that contains possible passphrases, and LUKS header backup. Makes it print progress info to standard error and continue. Sending a USR1 signal to a running bruteforce-luks process Then write the state to the file regularly (~ every minute). w Restore the state of a previous session if the file exists, m Maximum password length (beginning and end included).ĭefault: '0123456789ABCDEFGHIJKLMNOPQRSTU l Minimum password length (beginning and end included). f Read the passwords from a file instead of generating them. You can always get the source directly from bruteforce-luks GitHub repository. $ sudo dd if=/dev/sdb1 of=extended-luks-header bs=1M count=5ĥ242880 bytes (5.2 MB, 5.0 MiB) copied, 0.0273016 s, 192 MB/sĬreate a dictionary file with every possible passphrase combination, one per line.

Luks_header_backup: LUKS encrypted file, ver 1 UUID: ac32a865-2716-43e3-8db9-798d4279a3a3įor hashcat you will also need the first sector from the payload.

Store LUKS header backup as using the whole device can be very cumbersome. Perform a dictionary attack on the forgotten LUKS passphrase to access the encrypted device.
